 * Hi
 * FluentSMTP has been working brilliantly until at least a few days ago.
 * I am getting Unauthorized error when sending a test email (Microsoft account):
 * { “code”: 422, “message”: “Unauthorized”, “errors”: [ “Unauthorized” ] }
 * I also setup a separate SMTP account to send from but this is not working either:
 * { “code”: 422, “message”: “SMTP Error: Could not connect to SMTP host. Failed
   to connect to server”, “errors”: [ “SMTP Error: Could not connect to SMTP host.
   Failed to connect to server” ] }
 * I am on a GoDaddy managed wordpress package, there were several plugin updates
   recently but any help would be great.
 * Thanks

 * Hello [@garethpagesetup](https://wordpress.org/support/users/garethpagesetup/),
 * Based on the errors you’re seeing, and considering you’re on GoDaddy-managed 
   WordPress hosting, there are a few key areas we can investigate:
 * Here are a few potential reasons why you might be experiencing the error:
    1. **Incorrect App Callback URL:** Please double-check the URL you use to access
       the API endpoint provided by Fluent SMTP settings. Make sure that it is spelled
       correctly and includes any necessary parameters. This is a very common source
       of issues.
    2. **Insufficient permissions:** It is likely that the email address you are trying
       to use as the sender has no Mailbox created, has no permission to send emails,
       or it does not have any valid Office365 subscription. Ensure that the sending
       account has the necessary permissions within your Microsoft 365 setup.
    3. **Incorrect Account Type:** It is possible that you have selected the wrong 
       account type while creating the Azure App. It must be “Accounts in any organizational
       directory (Any Azure AD directory – Multitenant) and personal Microsoft accounts(
       e.g. Skype, Xbox)”. Double-check the settings within your Azure App registration.
    4. **Incorrect Logged-in Account:** When you click on the authorize button it asks
       you to log in to the Microsoft account and it should be using the same email
       or same account that is used to create the Azure App. Using the correct account
       during authorization is critical.
    5. **Domain Verification:** Also recheck that you have verified your domains inside
       Microsoft Office365. Unverified domains can lead to sending restrictions.
 * Regarding the “SMTP Error: Could not connect to SMTP host” message, since you’re
   on GoDaddy Managed WordPress, it’s possible they have specific restrictions on
   outbound SMTP connections. You might need to contact GoDaddy support directly
   to confirm if they allow connections to the SMTP host you’re trying to use and
   if there are any specific settings required for their environment. This error
   message is connected with network-level specifications like SMTP Port.
 * If none of these solutions resolve your issue, you may consult the Office 365
   API documentation here again: [https://fluentsmtp.com/docs/setup-outlook-with-fluentsmtp/](https://fluentsmtp.com/docs/setup-outlook-with-fluentsmtp/)
   or reach out to Microsoft Office365 Support for further assistance.
 * Please go through these points and let me know the results.
